Technical field
The present invention relates to a kind of chain-type window opener propulsion test device, be speciallyA kind of chain-type window opener plain type propulsion test device and method of testing。
Background technology
Window intelligent controller, has another name called window opener, is used in modern architecture, is used for realizing the intelligent artifact of automatic ventilation and fire-fighting link.
Along with the share of the market demand progressively expands, product needed high-volume JIT production, and ensure the qualified work being each production enterprise and paying attention to especially of the quality 100% of each product.At present, to one of the important technology index of traditional window opener mechanical performance, but ununified all the time evaluation criteria.And it is relatively big to be used for evaluating the mechanism for testing frictional force of mechanical performance, each product problem such as very inconvenient in cargo handling process is solved always, has a strong impact on the link of performance rating.
Summary of the invention
The purpose of the present invention is that to be provided to solve the problems referred to aboveA kind of chain-type window opener plain type propulsion test device and method of testing, the window opener test being applicable not only to various product size uses, and the convenient applying of used load and device self damping are very low, it is possible to very precisely test the thrust of chain-type window opener.
The present invention is achieved through the following technical solutions above-mentioned purpose: a kind of window control device simple type propulsion test device, including roller head, load, fixed support, bearing beam, power transmission shaft, window opener, window opener clamper, slides and fixesAdnexa;Roller head outside is engaged with support bracket fastened track and roller head mounted inside has rolling bearing, bearing beam and fixed support to be interconnected to constitute rolling friction transmission system;Counterweight load acts on composition gravitational load mechanism on bearing beam, and extraneous counterweight load can use standard type counterweight or sandbag;Window opener utilizes it to connectAdnexaIt is fixed on window opener clamper;After window opener powers up, the thrust of window opener output is on power transmission shaft;Power transmission shaft and bearing beam are connected with each other upwardly bearing beam;Slide fixingAdnexaIt is connected with each other with fixed support, for meeting the test of various sizes of window opener, slides fixingAdnexaInstallation can be moved left and right fixing.
Compared with testing device with existing window opener: the present invention arranges roller head, fixed support, bearing beam composition low resistance formula rolling system;Bearing beam and power transmission shaft belong to two-way gravity conduction device;When window opener mechanical mechanics property tested by needs, will be equipped with the counterweights such as the fixing counterweight of gravity, sandbag and act on bearing beam;Being passed through the input of power transmission shaft by its thrust on bearing beam by window opener, due to the action of gravity of counterweight self, window opener is pushed up overcoming the deadweight of its counterweight, realizes the purpose of test thrust with this.
This test device and method of testing are simply effective, it is not necessary to any linear bearing, test device the structure such as large-scale framework support, with low cost, and application is simple.

Detailed description of the invention
Below in conjunction withAccompanying drawingThe invention will be further described.
Such as Fig. 1Shown in, a kind of chain-type window opener simple type propulsion test device, including roller head 1, load 2, fixed support 3, bearing beam 4, power transmission shaft 5, window opener 6, window opener clamper 7, slides and fixesAdnexa8;The internal pre-buried rolling bearing of roller head 1, bearing beam 4, load 2, power transmission shaft 5 are interconnected to constitute rolling friction transmission system with fixed support 3;
Load 2 acts on composition gravitational load mechanism on bearing beam 4;Window opener 6 is connected by selfAdnexaIt is fixed on window opener clamper 7;The thrust powering up later stage output is passed through on power transmission shaft 5 at window opener 6;
Power transmission shaft 5 and bearing beam 4 are connected with each other;The roller head 1 being positioned at bearing beam 4 two ends is fixed with sliding by internal slide railAdnexa5 roll transmission, and fixed support 3 can be attached according to the size left and right sliding that window opener is concrete.
Further, should ensure that its levelness at roller head 1 and bearing beam 4 in assembling process, fixed support 3 should ensure that its flatness with the bearing beam equipped with roller head 1 in assembling process, it is prevented that roller head is unbalance stress in guide rail, skids off track.
Concrete test mode is: the thrust of test window opener.
Load 2 is placed the counterweight pre-set, and under gravity, bearing beam 4 is reduced to bottom under gravity;For direct current 24V chain-type window opener, when window opener is inputted forward voltage, be fixed on window opener clamper 7 at window opener 6 in advance, chain by with the linking of power transmission shaft 6, slowly upwardly;After this device assembles first, power transmission shaft 5 moves upward in process, observes the working order of roller head 1, it may be judged whether good in orbital path motion;Being automatically stopped when window opener 6 moves to its range, load 2 is raised to maximum height, and at this moment window opener 6 chain is under pressure;When applying backward voltage, load 2 gravitional force gradually reduces, until chain is taken in inside machine completely.
Window opener self-locking property is tested: for screw type window opener.
Apply forward voltage to be raised by bearing beam 4, when screw machine runs to stroke extreme value place, stop power supply, continue the weight of high load 2, observe the relative position relation of roller head 1 and fixed support 3, until moment is subjected to displacement, the weight of computational load 2, the weight of gained is the maximum self-lock force of screw machine.
The invention is not restricted to the thrust test of such as chain-type window opener, toothed bar type window latch, screw rod driven window opener; the bearing beam 4 of this device is replaced with window opener 6; applying load 2 at chain end, can test the pulling force of window opener 6, this device falls within protection scope of the present invention.
